[450HP]

The seat backs are bolted in... you remove the bottom portion of the seat and you'll see a bolt for each side of the seat back
at the bottom.

The bottom protion of the seat is held in by two clips that are welded to the floor.

You can feel under the front lip of the seat and find them, then you push away from you on the frame portion while lifting up.

This should release the bottom portion of the seat from it's catch.

Repeat for the other side.

Also make sure your seat belts are topside as they can cause a rattle.

Also check you upper mounts for your rear shocks, these too can cause a rattle.

Best of luck!
